[Abstract]:In order to improve the scanning frequency and delay time of fast optical delay line (FODL) device based on involute principle, an optical delay line device with high speed and high stability was proposed. The angle deflection and the optical path difference caused by the assembly error of the delay line device are analyzed. The scanning frequency, delay time, delay stationarity and delay linearity of the device are verified by Michelson interference system. The experimental results show that the assembly accuracy of the delay line device is high, and the high speed and high stability scanning and optical delay can be realized. The scanning frequency is 100 Hz, the delay time is 167.45 pss, the delay distance is 50.06 mm, the stationary error is 0.25 mm, and the linearity error is 0.05 mm.
